本文由搞代码简单介绍springboot全局异常拦截器友好异常提示简单案例演示
1、添加config 配置类
package com.gaodaima.config;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerExceptionResolver;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.view.json.MappingJackson2JsonView;
@Configuration
public class ExceptionConfiguration implements HandlerExceptionResolver {
@Override
public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler,
Exception ex) {
ModelAndView mv = new ModelAndView(new MappingJackson2JsonView()); //返回json
String exInfo = ex.toString().replaceAll("\n", "");
boolean status = exInfo.contains("Subject does not have permission");
if(status){
exInfo = "[没有此页面的访问权限]" + exInfo;
}else {
System.out.println("==============异常开始=============");
ex.printStackTrace();
System.out.println("==============异常结束=============");
}
mv.addObject("exception", exInfo);
mv.addObject("result", "exception");
return mv;
}
}
2、在逻辑类的方法上抛出异常 throws Exception，比如
/**删除
* @param out
* @throws Exception
*/
@RequestMapping(value="/delete")
@RequiresPermissions("autograph:del")
@ResponseBody
public Object delete() throws Exception{
Map<String,String> map = new HashMap<String,String>();
String errInfo = "success";
//xxxx
map.put("result", errInfo); //返回结果
return map;
}
3、前端页面接收异常结果
//发送 post 请求提交保存
$.ajax({
xhrFields: {
withCredentials: true
},
type: "POST",
url: httpurl+'xxxx/delete',
data: {tm:new Date().getTime()},
dataType:"json",
success: function(data){
if("success" == data.result){
}else if ("exception" == data.result){
alert("模块异常"+data.exception);//显示异常
}
}
});
